Unity 3D：5.2 version
TerrainCompose：1.92 version
RTP：3.2d version
Unity 3D 使用TerrainCompose 调用RTP 报错：
Can't access alphamapTexture directly...
UnityEngine.Debug:LogError(Object)
ReliefTerrain:GetControlMaps() (at Assets/ReliefPack/Scripts/ReliefTerrain/ReliefTerrain.cs:465)
ReliefTerrain:RefreshTextures(Material, Boolean) (at Assets/ReliefPack/Scripts/ReliefTerrain/ReliefTerrain.cs:273)
ReliefTerrainEditor:OnDisable() (at Assets/ReliefPack/Editor/ReliefTerrain/ReliefTerrainEditor.cs:124)
解决方案：
打开CS文件： Assets/ReliefPack/Scripts/ReliefTerrain/ReliefTerrain.cs 定位到457行；
将以下内容：
PropertyInfo info = terrainDataType.GetProperty("alphamapTextures", BindingFlags.Instance | BindingFlags.NonPublic);
修改为：
PropertyInfo info = terrainDataType.GetProperty("alphamapTextures", BindingFlags.Instance | BindingFlags.Public);
